SUBGENUS ALEURODICUS. 43 



two large hairs on caudal margin, one on either side. Size of 

 pupa case 1.3 by 0.92 mm. Shape broadly elliptical. Forewing 

 of adult (female) 2.27 mm. long, marked with dusky spots, six 

 forming a ring around the margin of the wing, two being cen- 

 tral. Segment V of antennae with a fringed sensorium and a 

 stout spine near its distal end. Waxy secretion of pupa a series 

 of fluted bands from simple wax pores, much longer than case 

 is wide, and from the compound wax pores are produced very 



long, curling, brittle, glassy wax rods neglectus. 



2. Dorsal disc without small simple pores, but the submarginal area all 

 around with very many, forming a band. 

 a. Exposed portion of lingula of pupa case long and spatulate; oper- 

 culum without a pair of spines on its caudal margin. 

 (1). Forewing of adult with one large central reddish brown marking 

 over the radial fork and extending from the costal margin to 

 or beyond the media. Length of forewing (female) 2.60 mm • 

 •genital segment of the male transversely wrinkled or striate! 

 Pupa case with submarginal row of stout hairs; size 1.30 by 

 0.70 mm. Shape elliptical. A prominent palisade of white wax 

 raises the case from the leaf. Dorsum void of secretion, except 



the glassy wax rods from comiwund wax pores ffii-ppmi 



(2). Forewing of adult with four transverse gray bands, of which 

 only the third and fourth are joined by a longitudinal band 

 (PI. XI\ ). Length of forewing (female) about 2.4 mm 

 Pupa case ovoid or subelli*ptical, variable in size, from 1 15 to 

 1.3 mm. long by 0.7 to 0.85 mm. wide. Dorsum of case powdered 

 with dirty white wax, and case raised by palisade of white wax 

 Lingula unusually large, dark brown in color _ __ dugcsii 

 6. Exposed portion of lingula of pupa case short and conical; caudal 

 margin of operculum with a pair of spines. 

 (1). Pupa case broadly elliptical, with two large, dark, latero-dorsad 

 areas extending the full length of the case. Margin entire 

 with a row of small simple pores some distance within it All 

 around on the submarginal area is a row of stout hairs. These 

 occur a considerable distance mdsad on the dorsum, some of 

 them almost between the compound pores; spinnerets of the 

 compound pores spread apart. Size of case 1.33 bv 115 

 mm , '. ' 



(2). Pupa case without dark latero-dorsad areas, but of uniform 

 yellowish color; margin entire and just within it a row all 

 around of large boat-shaped simple pores. A submarginal row 

 of long hairs present inserted in about the same region. Spin- 

 nerets of compound pores compact. Size of case variable, rang- 

 ing in length from 0.98 to 1.26 mm., and in width from 0.98 to 

 0.7 mm. Shape broadly oval, slightly narrower on cephalic end 

 Forewing of adult with two very faint dusky markings, one 

 extending from the costal margin over the radial fork, the 

 other at the apex of the wing. Length of forewing (female) 

 2.15 mm.; claspers of male very long and narrow. Immature 

 insects occurring along midrib of leaf and surrounded bv a 

 copious secretion of cottony-white wax__. _ cocois
